ADU’s are becoming a more popular option in Hawaii as people are realizing the many benefits that they offer. There are restrictions on who is able to build an ADU, but if you qualify, it can be very beneficial in a number of different ways. The basic requirements are:
- Your lot must be in residential zones 3.5, 5, 7.5,10, 20, and country districts.
- Your lot must be at least 3,500 square feet.
- The lot cannot be landlocked
- Your lot must have one single family dwelling.
- The property owner, or family of the owner must reside on the property.
- You will need to provide an extra parking stall in addition to the existing parking.
- Stay within the floor square foot limitations. 3,500-4,999 square foot lots can have a 400 square foot structure. Lots 5,000 and greater may have structures up to 800 square feet.
ADU’s in Hawaii allow homeowners to earn rental income, create more living space for family, allows our Kupuna to age in place, helps preserve the character of our neighborhoods and reduces the urban development on our Island.
Here in Hawaii we live on Islands with finite space and resources. Knowing this we must look at ways and options to keep our natural resources from being depleted, and find ways to keep our Islands a beautiful place for all of our children to enjoy in the future.
There is a lot we can do, and the ADU option is one of many positive benefits for us and our Islands. There is a huge amount of information online where you can also find all the pre-check forms to get started. An excellent source that I’ve found is hawaiiadu.org
